slub: remove invalid reference to list iterator variable
If list_for_each_entry, etc complete a traversal of the list, the iterator variable ends up pointing to an address at an offset from the list head, and not a meaningful structure. Thus this value should not be used after the end of the iterator. The patch replaces s->name by al->name, which is referenced nearby. This problem was found using Coccinelle (http://coccinelle.lip6.fr/). Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Pekka Enberg <penberg@kernel.org>
